The electrical power supply structure of today's power systems is changing towards high shares of renewable power supply. This leads to a decreased number of conventional power plants. However, conventional power plants still play a major role when it comes to voltage and frequency control. Thus, the remaining power plants in the system together with the renewable power supply units have to carry...
This paper presents a comparision between two controllers for Proton Exchange Membrane Fuel Cell PEMFC power system. The aim of this work is to keep the PEMFC working at its MPP by acting on the DC/DC converter, and ensure an adequate robustness against load and inputs variations. Conventional controller PI and backstepping technique are applied to the DC/DC boost converter. The stability of the backstepping...
Decentralized energy sources implement reactive power control strategies to reduce deviations of voltage magnitudes from nominal values at low- and medium-voltage levels. This paper studies the dynamics of a single Q(U)-controlled power converter that is connected to a grid. After introducing a model for converters that operate as current sources, a small-signal stability analysis is performed considering...
